The CHART II help system will be based upon using a browser to activate HTML files. These files will be context sensitive and contain hyperlinks. The illustration in figure 4-43 indicates a typical screen. One distinct advantage of using HTML for Help systems is the user need not start the application. The help system acts as the same way as a web server that can be opened by any browser with access to the files. The CHART II help system is incorporated in the delivered prototype system.
